This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This study identified distinctive trichoscopic features that may aid in diagnosing loose anagen hair syndrome, such as rectangular black granular structures, solitary yellow dots, and a predominance of follicular units with single hairs.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This review discusses genetic skin diseases in humans and animals, offering a resource for memorization and exploring animal models' role in understanding human disease mechanisms; it reports no new clinical results.

In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.

This study found that triglyceride and energy metabolic pathways are crucial factors influencing wool fiber diameter in fine-wool Alpine Merino sheep, providing insights for enhancing wool quality.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

This review discusses the formulations, mechanisms, and physiological aspects of hair cosmetics and types, but reports no new results, suggesting a foundation for future hair research.

This study suggests that PKCß plays a critical role in modulating the dermal inflammatory microenvironment in response to dietary lipids in mice.

This study demonstrates that genome-edited epidermal stem cells can continuously monitor blood glucose levels in vivo and potentially aid in diabetes treatment through skin somatic gene therapy.

This study identified that dominant mutations in the KLHL24 gene cause epidermolysis bullosa through dysregulated autoubiquitination, leading to excessive degradation of keratin 14.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

This study identified altered neurological pathways and potential drug targets involved in androgenetic alopecia, suggesting areas for future research and possible therapies.

This review traces the historical understanding and treatment of acne across ancient Egyptian, Greek, and Roman civilizations, but provides no new clinical findings.

This study generated FGF5-knockout Dorper sheep using the CRISPR/Cas9 system, resulting in significantly increased fine-wool and active hair-follicle density, and explored downstream signaling pathways for potential applications in androgen alopecia treatment.

This study identified a 582-bp deletion upstream of LHX2 in cashmere goats, likely linked to hair follicle development and cashmere production, providing insights into genetic factors in cashmere trait selection.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

This article reviews the molecular mechanisms involved in androgenetic alopecia and the androgen's paradoxical role in hair growth, but reports no new experimental findings.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

In this study, miR-218-5p was found to enhance hair shaft growth and positively regulate the Wnt signaling pathway by targeting SFRP2 during skin and hair follicle development.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

In this study, researchers identified genetic variants in the PCCA and PRLR genes that are significantly associated with hair coat length in Brangus heifers, potentially contributing to more thermotolerant cattle.

This study found that over half of the patients experienced varying degrees of hair loss after acromegaly surgery, with female patients and those with severe postoperative growth hormone deficiency more commonly affected.
